Tried one of the earlier fixes, https://boinc.loda-lang.org/loda/forum_thread.php?id=136

It seems like the loda-260125-windows-x86.exe executable file it looking for a DLLs called libcurl.dll and zlib1.dll.

To fix if I did the following:

1) cd to BOINC project directory(C:\ProgramData\BOINC\projects\boinc.loda-lang.org_loda)
2) Copy libcurl-260125-windows-x86.dll to libcurl.dll
3) Copy zlib1-260125-windows-x86.dll to zlib1.dll

After making these changes I pulled down new tasks and everything starting working normally.

Modified the copy to take into account v260314 naming and created the new files. Hasn't worked so it's not that.

I am seeing the same Error on all my Tasks on a Win 11 computer.

Have you tried resetting the project?

When it happens to me that the application crashes, I reset the project, then I update it and the problem gets fixed. It does not fix itself without manual intervention; once the application crashes on a WU, all subsequent WUs will go wrong until, in my case, I reset the project and start over, and then everything works, until the next time it happens again.

Yes have tried that.

And did you solve the problem?
